How does this skill handle database security?

It places databases on internal networks with no external access, enforces the use of environment files for credentials, and adds health checks to ensure the service is ready before dependent apps start.

Can I still make a service publicly accessible?

Yes. If you explicitly request public access, the skill will generate the appropriate binding but will include a warning reminding you to configure firewalls, TLS, and authentication.

Does it support resource management?

Yes, the skill automatically includes CPU and memory limits and reservations to prevent a single compromised or runaway container from crashing the entire host system.

Will it work with my existing Docker images?

Absolutely. It applies a standardized set of security wrappers (like read-only filesystems and capability dropping) that are compatible with most standard Docker images.

Why does this skill bind ports to 127.0.0.1 by default?

Binding to localhost prevents your services from being automatically exposed to the entire internet (0.0.0.0), which protects development servers and databases from automated scanners and remote attacks.

部署与 DevOps

Generates and hardens Docker Compose configurations using industry-standard security best practices to prevent unauthorized access and privilege escalation.

关于

This skill acts as a security-first architect for container orchestration, automatically injecting production-grade safeguards into your docker-compose.yml files. It enforces critical security principles such as localhost-only port binding, non-root user execution, and the prevention of privilege escalation. By automating the inclusion of health checks, resource limits, and network isolation, it helps developers build resilient, attack-resistant infrastructure without needing deep expertise in Docker security benchmarks.

主要功能

Resource limit definitions (CPU/Memory) to mitigate resource exhaustion and DoS.
Automatic localhost port binding (127.0.0.1) to prevent accidental public exposure.
Secure environment variable handling that discourages hardcoded secrets in YAML.
Mandatory security_opt configurations to block privilege escalation attacks.
0 GitHub stars
Network isolation patterns using internal drivers for backend and database services.

使用场景

Generating secure templates for databases like PostgreSQL and Redis with internal networking.
Hardening development Docker configurations for secure production deployment.
Auditing existing Docker Compose files to identify and fix common security vulnerabilities.
